The pink river dolphin (Inia geoffrensis), also known as the Amazon river dolphin, is an enigmatic species found exclusively in the freshwater rivers of the Amazon Basin. Characterized by its distinctive pink coloration and long, flexible rostrum, this dolphin species is adapted to the complex riverine environment of the Amazon.

Unlike marine dolphins, the pink river dolphin inhabits slow-moving rivers and flooded forests, where it relies on its keen echolocation skills to navigate and hunt for fish. Its unique coloration, which can range from pale pink to a deep rosy hue, is thought to result from the presence of blood vessels near the skin’s surface.

Conservation challenges for the pink river dolphin include habitat loss due to deforestation, water pollution, and the impact of human activities such as fishing and river traffic. Protecting this species involves efforts to mitigate human impact on its habitat, promote sustainable river practices, and enhance research on its behavior and ecology.
